The standard and essentially only commercial condition: high-pressure die cast and used as-cast, no heat treatment (heating risks blistering from entrapped gas).
What is A413-F?
A413-F is A413 in the F temper — the standard and essentially only commercial condition: high-pressure die cast and used as-cast, no heat treatment (heating risks blistering from entrapped gas). A413-F has a yield strength of 130 MPa (18.9 ksi) and a tensile strength of 290 MPa (42.1 ksi) — weaker than 74% of aluminum grades. Elongation at break is 3.5% and the elastic modulus is 71 GPa (10.3 Msi). A413-F has a density of 2.66 g/cm³ (0.0961 lb/in³), lighter than 84% of aluminum grades. It melts at 574°C (1,065 °F).
Limitations
- Low fracture toughness — 17 MPa·√m (15.5 ksi·√in), worse than 83% of aluminum grades

Working with A413-F
Is A413 easy to machine?
Abrasive eutectic silicon demands PCD or diamond-coated carbide tooling, high speed with low feed, and flood coolant; chips are short and it drills/taps acceptably but tool life is far below 6061.
Can A413 be welded?
Base alloy is fusion-weldable with 4047/4043 filler, but high-pressure die castings contain entrapped gas — expect porosity and blistering; prefer mechanical joining, adhesive bonding or friction-stir/laser for thin sections.
Can A413 be formed, bent or molded?
High-pressure die casting alloy with outstanding fluidity, low shrinkage and excellent hot-tear resistance — ideal for thin walls (≥1 mm) and pressure-tight housings; not intended for heat treatment or cold forming.
What surface finishes work on A413?
Anodizes to a dark, uneven grey because of the silicon phase; use chromate/phosphate conversion coating, e-coat, powder coat or electroless nickel for appearance and corrosion protection.

A413-F — frequently asked
What is A413-F used for?
A413-F is typically used for pressure castings, marine fittings and pumps. In short: eutectic Al-Si die cast.
What is the yield strength of A413-F?
A413-F has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 290 MPa (42.1 ksi) — weaker than 74% of aluminum grades.
Is A413-F easy to machine?
Not especially — machinability is rated fair (40/100, worse than 80% of aluminum grades). Abrasive eutectic silicon demands PCD or diamond-coated carbide tooling, high speed with low feed, and flood coolant; chips are short and it drills/taps acceptably but tool life is far below 6061.
Can A413-F be welded?
With care — weldability is rated fair (45/100). Base alloy is fusion-weldable with 4047/4043 filler, but high-pressure die castings contain entrapped gas — expect porosity and blistering; prefer mechanical joining, adhesive bonding or friction-stir/laser for thin sections.
What surface finishes work on A413-F?
Anodizes to a dark, uneven grey because of the silicon phase; use chromate/phosphate conversion coating, e-coat, powder coat or electroless nickel for appearance and corrosion protection.
Can A413-F be formed, bent or molded?
High-pressure die casting alloy with outstanding fluidity, low shrinkage and excellent hot-tear resistance — ideal for thin walls (≥1 mm) and pressure-tight housings; not intended for heat treatment or cold forming.
What is the maximum service temperature of A413-F?
A413-F is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
